This won't answer your question as to where to farm good gear, but where to possibly farm good gold.
Red eye golems in the caves have always dropped well for me getting 3/4 drops per booster pretty often. The only "good" gear there is the -10 NS weap (which is the only item I bother opening), but at that rate of item drops I made a lot, (i wanna say over 400mil in an hour but I might be remembering wrong because its been awhile), just npc'ing them all. That isn't subtracting the cost of the few pots I used.
Doesn't really solve where to drop your gear but it can put a bit of gold in your pockets to purchase any of that gear that may be for sale by another player. Complete band-aid solution, I know, because if the gear isn't dropping no one is selling, but, as the ppl that do have it level out of it they may sell and there ya go.
Think I'll do some drop farming there tonight and see since I haven't done it since these couple of last patches.
